IMPROVEMENT IN EYELET-MACHINES.

Specification forming part of` Letters Patent No. 32,088, dated April16,1861.

To @ZZ whom it may concern: I

Be it known that I, SAMUEL J. SMITH, of the city and State of New York,have invented, made, and applied to use a certain new and usefulImprovement in Eyelet-Machines; and I do hereby declare that thefollowing is a full, clear, and exact description ot the constructionand operation ot' the same, reference being had to the annexed drawing,making part of this specilication,in which I have rep resented aVertical section of my improved eyelet-machine.

In the ordinary eyelet-machines a cam or level' is used to force thepunch or cutter through the material. This, however, is found to beobjectionable because such cam or lever tends to press the punch to oneside and interfere with the same entering the hole or die correctly.

The nature of my said invention consists in an arrangement of percussiondie o r cutter constructed ina cylindrical form and applied in such amanner that said die or cutter is free to turn around while in use andbe perfect in its operation in the hole or die, instead of constantlywearing in one direction and becoming untrue. V

In order to produce the necessary power for the purposes of cutting orstriking up the eyelet, I make use of a perforated ball sliding upon thecircular stock of the die or cutter, so as to give a blow or concussionsufliciently powerful to either perforate the material with the cutteror strike up the eyelet with the punch or die.

In the drawing, ct is the base of the press, and ZJ is a standard.

c is an arm perforated vertically, as represented, receiving thecylindrical stock d of the cutter 3, and this arm is adapted to containthe helical spring I, taking the pin 2 to elevate the cutter, and alsothe cap e, that is screwed into the arm, as shown, to guide the stock orstern d of the cutter 3, and 4 is the hole or opening into which thecutter passes as the perforation of any article is accomplished by ablow upon the end of (l. It will now be seen that the whole of the die3, shank d, and cap c can be turned, and that the parts in the arm c canbe bored out. Thus the construction is simple and cheap, but thev actionof the parts will bel perfectly true. The die 7 (acting in the hole S tostrike or swage up an eyelet in the ordinary way) is upon the stem g inthe other arm c, and is provided with the spring 5, pin 6, and cap 71the same as the parts d, c, l, and 2, except that the stem g is extendedup and receives upon a shoulder loosely the perforated ball fz, byelevating which and then striking it down forcibly will produce a blowor concussion sufficient for either perforating or striking up theeyelets.Y

forated arm c, as specified, and the percussion-ball t' in combinationforth. In witness whereof I have hereunto set my signature this 2d dayof March, 1861.
